HINGE.

Specification of Letters Patent.

Application filed April 18, 1910. Serial No. 555,227.

To all whom it may concern:

Be it known that I, JAMES WV. SHINE, a citizen of the United States, residing at Macon, in the county of Bibb and State of Georgia, have invented a new and useful Hinge, of which the following is a specification.

It is the object of the present invention to provide an improved hinge designed primarily for use in hanging window blinds, the object of the invention being to provide a hinge for this purpose which will securely hold the blind at any desired position between its open and closed positions and also in full closed position.

Another object of the invention is to so construct the hinge that the pintle of the hinge cannot be removed when the blind is in closed position and in view of this fact and the fact that the device for holding the blind at various positions between its open and closed positions is so located that it will be concealed when the blind is closed, the removal of the blind by any one attempting to enter through the window with which it is associated Wlll be rendered practically impossible unless indeed the blind is destroyed.

It is another object of the invention to so construct the means for holding the blind at various positions, that it may be rendered inoperative at will so that where it is not desired to lock the blind at any one position, the same will be free to swing back and forth upon its hinges.

With the above and other objects in view, the invention consists in the construction and arrangement of parts substantially as shown and described in the accompanying drawings, in which,-

Figure 1 is a view in elevation of a hinge constructed in accordance with the present invention. Fig. 2 is a top plan view thereof, the latch for the hinge leaves being shown in one position in full lines and in another osition in dotted lines. Fig. 3 is a vertical sectional view on the line 3-3 of Fig. 1-. Fi 4 is a horizontal section on the line 4-4 0 Fig. 1. Fig. 5 is a vertical section throu h the knuckles of the hinge.

In the rawings, one of the hinge leaves is indicated by the numeral 6 and the other by the numeral 7 and these leaves are formed respectively with knuckles 8 and 9. The hinge leaves are connected by a pintle pm 10 which is inserted through the knuckles when the said knuckles are alined, and this pintle pin is formed at its upper end with a Patented Jan. 3, 1911.

head 11 which limits its downward movement through the knuckles and is formed adjacent its said head with an outstanding boss which is indicated by the numeral 12, and in order to ermit of the insertion of the pin throu h t e openings of the knuckles or more speci call to accommodate the boss 12, the said knuck es are stamped out, as indicated by the numeral 13, so that their stamped-out portions will aline and afford a groove when the hinge leaves are in such relative position as they would assume were the blin to which they are to be applied, in open position. With the leaves in this relative position, the pin is inserted and, of course, when the leaves are swung upon the pintle pin and assume any position other than that just mentioned, the struck-out portions of the knuckles will be out of registration, and as a result, withdrawal of the pintle pin from the knuckles will be effectually prevented. Consequently, when the blind which the hinge supports, is in open position, the pintle pin maybe removed for the purpose of dismounting the blind.

The means for holding the hinge leaves at various relative positions between the position they assume when the blind is open or closed, includes a notched disk, which is inmgs, which slot receives or engages with the hinge leaf 6, and on the other hand, the

hinge leaf 7 is formed with a slot which is indicated by the numeral 17 and which receives, movably, the said disk 14, the knuckles 9 of the said hinge leaf 7 being spaced apart a distance only sufiicient to receive between them the disk. Also, the disk is formed axially with an opening 18 for the passage of the pintle pin 10. With the parts so formed, after the hinge leaves 6 and 7 have been assembled with their knuckles alined the disk 14 is inserted into place, as illustrated in the horizontal sectional view of the drawings, and the pintle pin 10 is then fitted through the openings of the knuckles and the opening in the disk 14. With the parts thus assembled, as will be readily understood, the. hinge leaf 7 may be swung about the pintle pm 10 whereas the disk 14 -tion of the will be held fixed with respect to the hinge leaf 6, which hinge leaf, it is intended, shall be applied to the window frame.

A spring latch cooperates with the notches of the disk 14 whereby to hold the hinge leaf at adjustment, as heretofore stated, and this hinge latch has its body ortion indicated by the numeral 19 in the rawings and slidably held between stamped-up guides 20 constituting a' part of the hinge leaf 7, one end of this body being desi ned to engage in the notches 15 interchangea ly and the other end being formed with a stem portion which is bent to extend outwardly at right angles, as at 21, and thence laterall at right angles, as at 22, and through a ange 23 formed by bending u at ri ht angles the outer porl linge eaf 7. A spring 24 is fitted upon the portion 22 of the stem of the latch and bears against the portion 21 and against the flange 23, the function of this spring being to hold that end of the latch body opposite the end from which the stem pro ects, in engagement with the notches in the periphery of the disk 14. The portion 22 of the stem is rounded and fitted rotatably thereon is a collar 25 which is formed with a cam groove 26 into which groove projects the extremity 27 of an over-turned projection 28 upon the edge of the flange 23. A disk-like head 29 is integral with the collar 25 at its outer end and the extremity of the stem 22 is headed and retains the said collar and head thereon. It will be readily understood that by rotating the head 29, the stem 22 will be drawn to the right in Flg. 2 of the drawings, or be allowed to move to the left under the action of the spring 24, depending of course upon the direction of rotation of the said head.

From the foregoing description of the invention it will be readily understood that while the hinge leaf 6 is to be secured to the' window frame, the leaf 7 is to be secured to the blind and that whereas the head 29 may be rotated so as to retract the latch 19, or in other words move it out of position for engagement in the notches in the disk 14, and thereby permit of the blind being swung below upon its hinge, the said head may be rotated so as to allow the spring 24 to hold the latch end in engagement with any one of the notches for the purpose of holding the blind at any desired position between its open and closed positions. It will further be understood from inspection of Fig. 5 of the drawings that the hin e may be used upon either a right or a le t hand blind b merely inverting the same and correspon lngly reversing the insertion of the pintle pin through the alined openings of the knuckles.

What is claimed is 1- In a hinge, connected leaves, a notched disk rigid with respect to one of the leaves and a latch carried by the other hinge leaf and engageable with the notches in the said disk, the last mentioned hinge leaf having a flange and the latch having a stem fitting slidably through the flange, the stem bein formed with a shoulder, a spring dispose upon the stem and hearing at one end' against the shoulder thereon and at its other end against the flange, a collar rotatably fitted upon the stem and formed with a cam groove, the said hinge leaf upon which the atch is mounted being formed with an overturned portion upon its flange riding in said groove, and means whereby the collar may be rotated to withdraw the latch from engagement in the notches against the tension of the said s ring.

In testimony t at I claim the foregoing as my own, I have hereto aflixed my slgnature in the presence of two witnesses.
